Fig. 1 shows a schematic diagram of a network architecture provided by an embodiment of the present application. As shown in FIG. 1, the communication system of the embodiment of the present application may include network equipment (for example, gNB) and terminal equipment (for example, UE1 to UE6). The network device can include one antenna or multiple antennas. In addition, the network device may additionally include a transmitter chain and a receiver chain. Those of ordinary skill in the art can understand that they can all include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, Demodulator, demultiplexer or antenna, etc.). FIG. 1 is only a simplified schematic diagram of an example. The number of terminal devices in the communication system of FIG. 1 is only for illustration. The number of terminal devices in the communication system may be other numbers. In addition, the communication system may also include other communication devices, as shown in FIG. 1 Not shown in the drawing. In the communication system, terminal devices (such as UE1 to UE6) can send uplink signals to network devices (such as gNB) based on the frequency hopping pattern, and the network devices (such as gNB) can receive the uplink signals. In this communication system, a network device (for example, gNB) can send downlink signals to terminal devices (for example, UE1 to UE6) based on a frequency hopping pattern.

In the embodiments of the present application, data or information may be carried by time-frequency resources, where the time-frequency resources may include resources in the time domain and resources in the frequency domain, that is to say, the network equipment and the terminal equipment can pass through Time-frequency resources for data transmission. The time-frequency resource used for data transmission can be represented as a resource grid. Figure 2 shows a schematic diagram of a resource grid. In the resource grid as shown in FIG. 2, a resource element (resource element, RE) is the smallest resource unit used for data transmission, or RE is the smallest resource unit used for resource mapping of data to be sent. As shown in Figure 2, an RE corresponds to a symbol in the time domain, such as orthogonal frequency division multiplexing (OFDM) symbols or discrete fourier transform spread orthogonal frequency division multiplexing (discrete fourier transform spread orthogonal frequency division) Multiplexing (DFT-s-OFDM) symbols, one RE corresponds to one subcarrier in the frequency domain. One RE may be used to map a complex symbol, for example, a complex symbol obtained through modulation, or a complex symbol obtained through precoding, which is not limited in the embodiment of the present application. In FIG. 2, a time slot may include 14 time domain symbols, and a resource block (RB) may correspond to 12 subcarriers in the frequency domain. It should be understood that FIG. 2 is only a schematic diagram of a possible time-frequency resource, and the specific form of the time-frequency resource is not limited in the embodiment of the present application.

The terminal device can transmit the uplink signal according to the frequency hopping pattern, and the frequency hopping pattern determines one of the code domain resource unit (for example, sequence), time domain resource unit (for example, symbol), and frequency domain resource unit (for example, subcarrier) corresponding to the uplink transmission. Item or multiple items. The terminal device maps the uplink signal (for example, one or more code domain resource units) to the corresponding time domain resource unit and/or frequency domain resource unit for transmission. In the frequency hopping pattern, different time domain resource units may correspond to different frequency domain resource units, and/or different time domain resource units may correspond to different code domain resource units. The network device receiving the uplink signal may be receiving the uplink signal of one or more terminal devices according to the frequency hopping pattern.

The preamble transmission is taken as an example to illustrate the frequency hopping pattern.

The terminal device can perform multiple repeated PRACH transmissions, or it can also be understood that the PRACH preamble can be repeatedly sent in the time domain, and the frequency domain resource of the PRACH preamble transmitted each time can be determined according to the frequency hopping pattern. Determining the frequency domain resource of each PRACH preamble transmission in the PRACH repeated transmission according to the frequency hopping pattern can also be understood as mapping the sequence corresponding to the PRACH preamble to the time-frequency resource used for PRACH transmission according to the frequency hopping pattern.

For example, the time domain resource of a PRACH preamble transmission may include 4 symbol groups. A symbol group can contain multiple time domain symbols. Fig. 3 shows an example diagram of a random access symbol group. As shown in FIG. 3, a symbol group includes _{a cyclic prefix with a length of T CP} and multiple time domain symbols with a total length of T _SEQ. If the PRACH preamble needs to be repeatedly transmitted twice, the time domain resource for PRACH preamble transmission includes 8 symbol groups. The frequency domain resources that can be used for PRACH preamble transmission may include multiple subcarriers. For example, the frequency domain resources that can be used for PRACH preamble transmission may include 12 subcarriers, and the 12 subcarriers are respectively numbered {0,1,2,3,4,5,6,7,8,9,10,11 }. The frequency domain resource corresponding to each symbol group in one PRACH preamble transmission is one of the above-mentioned 12 subcarriers. Specifically, the frequency domain resource corresponding to a symbol group may be determined by the frequency hopping pattern.

Network equipment usually configures different frequency hopping patterns for different terminal devices, and different frequency hopping patterns have no overlapping parts. If terminal device A and terminal device B repeatedly transmit the PRACH preamble twice on the same time-frequency resource, that is to say, terminal device A and terminal device B transmit 8 symbol groups on the same time-frequency resource, each symbol group The corresponding frequency domain resource is one of the above 12 subcarriers. The frequency hopping patterns of the terminal device A and the terminal device B do not overlap, that is, for the terminal device A and the terminal device B, the frequency domain resources corresponding to any one of the eight symbol groups are different. For example, the numbers of the subcarriers transmitting 8 symbol groups by terminal device A are {3,4,10,9,7,8,2,1}, and the numbers of the subcarriers transmitting 8 symbol groups by terminal device B are respectively {7,8,3,4,6,7,10,9}.

In the above solution, the number of completely non-overlapping frequency hopping patterns is the number of subcarriers corresponding to PRACH, that is, a total of 12 non-overlapping frequency hopping patterns can be supported. In order to improve the resource utilization efficiency of PRACH transmission, different from the aforementioned network equipment that configures different frequency hopping patterns for different terminal devices, the terminal device can randomly select a frequency hopping pattern from the above 12 frequency hopping patterns, and according to the frequency hopping pattern Transmit PRACH preamble. When the network device detects the frequency hopping pattern, it can notify the terminal device that selected the frequency hopping pattern to send the ID of the terminal device to complete the terminal device's access.

In the above case, when more terminal devices send the preamble at the same time, the frequency hopping pattern is randomly selected, and the probability of collision is greater, that is, the probability that at least two terminal devices select the same frequency hopping pattern to send the preamble is greater . For example, if the number of subcarriers is 12, when 4 terminal devices transmit the preamble at the same time, the collision probability is as high as 42.7%.

If two terminal devices select the same frequency hopping pattern, the network device cannot distinguish the two terminal devices on the receiving side, and thus cannot complete the access of the two terminal devices.

In the embodiment of the present application, a·b, ab, or a×b all represent the multiplication of two numbers, and a mod b represents a modulo operation.

FIG. 4 shows a schematic diagram of a communication method 400 in an embodiment of the present application. The method 400 includes steps 410 to 430. Steps 410 to 430 will be described in detail below.

The terminal device or the network device maps the first data according to the first frequency hopping pattern, where the first frequency hopping pattern is one of K candidate frequency hopping patterns, and one of the K candidate frequency hopping patterns includes L frequency hopping units, at least two of the K candidate frequency hopping patterns include the same frequency hopping unit, K is an integer greater than 1, and L is an integer greater than 1.

Or it can also be understood that there is overlap between at least two candidate frequency hopping patterns among the K candidate frequency hopping patterns. The resource used for mapping the first data is determined by the frequency hopping unit in the first frequency hopping pattern. Wherein, the resource may include one or more of time domain resources, frequency domain resources, or code domain resources.

The sub-frequency hopping pattern is one of the H candidate sub-frequency hopping patterns, and one candidate sub-frequency hopping pattern of the H candidate sub-frequency hopping patterns includes a plurality of sub-frequency hopping units. H is an integer greater than 1. This embodiment is described in detail in Form 3 below.

Or it can also be understood that a frequency hopping unit corresponds to a frequency domain resource unit in the frequency domain and a time domain resource unit in the time domain. In the time-frequency resource unit composed of the frequency domain resource unit and the time domain resource unit One frequency hopping unit corresponds to one sub-frequency hopping pattern in the time-frequency resource unit, that is, the frequency hopping unit includes multiple sub-frequency hopping units in one sub-frequency hopping pattern in the time-frequency resource unit.

The frequency domain resource unit used for mapping the first data may be the same or different on different time domain resource units. The sub-frequency hopping patterns used to map the first data may be the same or different on different time domain resource units. Wherein, in a time domain resource unit, the resource used for mapping the first data is determined by the sub-frequency hopping unit in the sub-frequency hopping pattern.

In a possible implementation of the frequency hopping unit, a frequency hopping unit includes a time domain resource unit in the time domain, and the frequency hopping unit corresponds to a sub-frequency hopping pattern on the time domain resource unit. The sub-frequency hopping pattern is one of multiple candidate sub-frequency hopping patterns, and one candidate sub-frequency hopping pattern of the multiple candidate sub-frequency hopping patterns includes multiple sub-frequency hopping units.

Or it can be understood that a frequency hopping unit corresponds to a time domain resource unit in the time domain, and can correspond to a frequency domain resource that can be used to map the first data in the frequency domain, and the frequency domain resource and the time domain resource unit constitute In the time-frequency resource, one frequency hopping unit corresponds to a sub-frequency hopping pattern in the time-frequency resource, that is, the frequency hopping unit includes multiple sub-frequency hopping units in a sub-frequency hopping pattern in the time-frequency resource.

The sub-frequency hopping patterns used to map the first data may be the same or different on different time domain resource units. Wherein, in a time domain resource unit, the resource used for mapping the first data is determined by the sub-frequency hopping unit in the sub-frequency hopping pattern.

420. In the case that step 410 is that the terminal device maps the first data according to the first frequency hopping pattern, step 420 is that the terminal device sends the first data to the network device or the terminal device.

In the case that step 410 is that the network device maps the first data according to the first frequency hopping pattern, step 420 is that the network device sends the first data to the terminal device.

430. In the case that step 410 is that the terminal device maps the first data according to the first frequency hopping pattern, step 430 is that the network device or the terminal device demaps the first data according to the first frequency hopping pattern.

In the case that step 410 is that the network device maps the first data according to the first frequency hopping pattern, step 430 is that the terminal device demaps the first data according to the first frequency hopping pattern.

For example, the network device or the terminal device may use a compressed sensing algorithm to detect the first data.

It should be understood that the method 400 in the embodiment of the present application is not only applicable to the uplink transmission between the terminal device and the network device, but also applicable to the downlink transmission between the network device and the terminal device, and also applicable to the transmission between the terminal devices. In FIG. 4, only the uplink transmission between the terminal device and the network device is used as an example to illustrate the method 400, which is not regarded as a limitation to the embodiment of the present application.

According to the solution of the embodiment of the present application, at least two candidate frequency hopping patterns in the K candidate frequency hopping patterns include the same frequency hopping unit, that is, overlap between the K candidate frequency hopping patterns is allowed. The terminal equipment or network equipment can select a frequency hopping pattern from K candidate frequency hopping patterns to map the first data, which increases the number of candidate frequency hopping patterns that the terminal equipment and network equipment can support, and reduces the terminal equipment or network equipment's The possibility of conflicts during signal transmission, thereby increasing the access capacity. For example, when performing preamble transmission, it is possible to reduce the probability of collisions when randomly selecting candidate frequency hopping patterns, increase the success probability of terminal device access, and thereby increase the number of terminal devices that can be simultaneously accessed.

The frequency hopping unit may include multiple forms, and the following descriptions are only given in three forms (form 1, form 2, and form 3) of the frequency hopping unit, which should not be regarded as a limitation to this application.

Form 1: In a possible implementation of the frequency hopping unit, a frequency hopping unit includes a frequency domain resource unit in the frequency domain, and the frequency hopping unit includes a time domain resource unit in the time domain.

Form 2: In a possible implementation of the frequency hopping unit, a frequency hopping unit includes a frequency domain resource unit in the frequency domain, and the frequency hopping unit includes a time domain resource unit in the time domain, and the hopping unit includes a time domain resource unit in the time domain. The frequency unit includes a code domain resource unit in the code domain.

The frequency unit corresponds to a sub-frequency hopping pattern on the frequency domain resource unit and the time domain resource unit. The sub-frequency hopping pattern is one of the H candidate sub-frequency hopping patterns, and one candidate sub-frequency hopping pattern of the H candidate sub-frequency hopping patterns includes a plurality of sub-frequency hopping units. H is an integer greater than 1.

The three forms of the frequency hopping unit will be described in detail below.

Form 1

A frequency hopping unit includes a frequency domain resource unit in the frequency domain, and the frequency hopping unit includes a time domain resource unit in the time domain.

Or it can also be understood that the candidate frequency hopping pattern can determine frequency domain resource units corresponding to different time domain resource units.

Specifically, the frequency domain resources that can be used to map the first data may include M frequency domain resource units. The frequency domain resource units included in the frequency domain resources that can be used to map the first data can be understood as candidate frequency domain resource units. The frequency domain resource unit corresponding to one frequency hopping unit is one of the above M frequency domain resource units. A candidate frequency hopping pattern may include L frequency hopping units. L may be equal to the number of time domain resource units included in the time domain resource used for mapping the first data. The terminal device or the network device maps the first data to the time-frequency resource corresponding to the first frequency hopping pattern. The first frequency hopping pattern is one of a plurality of candidate frequency hopping patterns. A candidate frequency hopping pattern is used to determine the frequency domain resource unit corresponding to each of the L time domain resource units.

Exemplarily, one time domain resource unit may include at least one frame, at least one subframe, at least one time slot, at least one mini-slot, or at least one time domain symbol, etc., which is not limited in the embodiment of the present application.

Exemplarily, one frequency domain resource unit may include at least one carrier, at least one component carrier, at least one bandwidth part, at least one resource block group, at least one physical resource block group, at least one resource block, or at least one subcarrier. The embodiment of the application does not limit this.

As mentioned above, one time domain resource unit may include multiple time domain symbols. For example, the multiple time domain symbols may correspond to a physical random access channel (PRACH) symbol group.

Exemplarily, when one time domain resource unit is one PRACH symbol group, and one frequency domain resource unit is one subcarrier, the candidate frequency hopping pattern determines the subcarriers corresponding to different PRACH symbol groups.

The frequency hopping pattern is described below by taking a time domain resource unit as a PRACH symbol group, a frequency domain resource unit as a subcarrier, and the first data being a PRACH preamble as an example.

For example, the time domain resource of a PRACH preamble transmission may include 4 PRACH symbol groups, L may be equal to the number of PRACH symbol groups, and L is 4, that is, a candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarriers transmitted by each PRACH symbol group in the 4 PRACH symbol groups.

For another example, the time domain resource for a PRACH preamble transmission may include 4 PRACH symbol groups, and for repeated PRACH preamble transmissions twice, 8 PRACH symbol groups are required, that is, the time domain resources for two PRACH preamble transmissions include 8 PRACH symbol groups. In this case, L may be equal to the number of time domain resource units included in the 8 PRACH symbol groups, that is, L is 8. A candidate frequency hopping pattern includes 8 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarriers transmitted by each PRACH symbol group in the 8 PRACH symbol groups.

Exemplarily, when one time domain resource unit is one time slot and one frequency domain resource unit is one subcarrier, the candidate frequency hopping pattern determines the subcarriers transmitted in different time slots.

The frequency hopping pattern will be described below by taking one time domain resource unit as a time slot, one frequency domain resource unit as a subcarrier, and the first data being a PRACH preamble as an example.

For example, the time domain resource for one PRACH preamble transmission may include 1 time slot, and the time domain resource for repeated PRACH preamble transmission 4 times includes 4 time slots. In this case, L may be equal to the number of time domain resource units contained in 4 time slots, that is, the number of repeated transmissions of the PRACH preamble, that is, L is 4. A candidate frequency hopping pattern includes 4 frequency hopping units, and the time-frequency resource of a PRACH preamble transmission is a frequency hopping unit. The candidate frequency hopping pattern is used to determine the subcarriers transmitted in each of the 4 time slots.

When the time resource unit corresponding to the frequency hopping unit can transmit a complete signal, the frequency hopping unit can ensure that the network device or terminal device can detect whether a signal is being transmitted, so as to detect the terminal device or network device. For example, when a time domain resource unit is a time slot and the first data is a PRACH preamble, one time slot can transmit a complete PRACH preamble, and the network device can detect whether a signal from a terminal device is being transmitted, so that The terminal device is detected.

Optionally, the index of the aforementioned frequency domain resource unit may be preset.

Specifically, by determining the index of the frequency domain resource unit and the index of the time domain resource unit of a frequency hopping unit, the position of the frequency hopping unit on the time-frequency resource available for the first data transmission can be determined. Further, by determining the index of the frequency domain resource unit and the index of the time domain resource unit of the L frequency hopping units in a candidate frequency hopping pattern, the positions of the L frequency hopping units on the above-mentioned time-frequency resource can be determined. For ease of description, the position of the frequency hopping unit on the time-frequency resource available for the first data transmission may also be referred to as the position of the frequency hopping unit.

The preset index of the frequency domain resource unit can also be understood as the correspondence between the index of the preset frequency domain resource unit of the frequency hopping unit and the index of the time domain resource unit of the frequency hopping unit.

For example, the index of the frequency domain resource unit can be obtained through a predefined table, or it can be said that candidate frequency hopping patterns are obtained through a predefined table. Table 1 shows a predefined table of candidate frequency hopping patterns. It should be understood that Table 1 is only for illustration, and the embodiment of the present application does not limit the correspondence between the index of the frequency domain resource unit and the index of the time domain resource unit. Specifically, the predefined table can give the positions of L frequency hopping units in a candidate frequency hopping pattern, that is, give the frequency domain resource unit positions and time domain resource unit positions corresponding to the L frequency hopping units, or give The index of the frequency domain resource unit and the index of the time domain resource unit corresponding to the L frequency hopping units are obtained. That is to say, the candidate frequency hopping pattern obtained through the predefined table can be understood as the predefined table gives the corresponding frequency domain resource unit on each time domain resource unit, or in other words, gives the corresponding frequency on each time domain resource unit. The index of the domain resource unit.

Alternatively, the index of the frequency domain resource unit may also be calculated according to a certain rule.

Optionally, the index of the frequency domain resource unit mentioned above is related to L.

Optionally, the index of the frequency domain resource unit is also related to M.

Optionally, the index of the aforementioned frequency domain resource unit satisfies:

Further, one time domain resource unit may include N OFDM symbols, and the index of the OFDM symbol may be from 0 to N-1.

As mentioned above, the index of the frequency domain resource unit corresponding to the lth time domain resource unit determined by the kth candidate frequency hopping pattern is the frequency domain resource unit m _k,l , that is to say, at the kth candidate frequency hopping pattern The corresponding frequency domain resource unit in each OFDM symbol in the l th time domain resource unit in the pattern is a frequency domain resource unit m _k,l . Map x(n) on the nth OFDM symbol in the lth time domain resource unit, and then generate the OFDM symbol.

The sequence x(n) can be a predefined sequence.

Further, the sequence x(n) may be a complex number sequence.

Among them, n is the index of the symbol in the time domain resource unit, n is an integer less than or equal to N-1, j is an imaginary unit, the square of j is equal to -1, and π represents the circumference of the circle.

It can be stipulated by the agreement or set in advance.

All frequency hopping units in the K candidate frequency hopping patterns may include the same code domain resource unit in the code domain. Wherein, the code domain resource unit may be a sequence.

For example, all frequency hopping units in the K candidate frequency hopping patterns may have the same sequence in the code domain. In the following, one time domain resource unit is used as a time slot, one frequency domain resource unit is used as one subcarrier, and the first data is a PRACH preamble as an example to describe the index of the above frequency domain resource unit.

Exemplarily, the time domain resource for one PRACH preamble transmission may include one time slot, and the frequency domain resource may include one subcarrier. The PRACH preamble is repeatedly sent L times in the time domain, and each time a frequency hopping unit can be used for transmission, that is, the time domain resource of one transmission includes 1 time slot, and the frequency domain resource includes 1 subcarrier. The time domain resource for repeated PRACH preamble transmission L times includes L time slots. L can be 4, that is, a candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the corresponding subcarrier on each of the 4 time slots. The frequency domain resources that can be used for PRACH preamble transmission include 12 subcarriers, and M is 12. The terminal device can select one candidate frequency hopping pattern from the K candidate frequency hopping patterns to transmit the PRACH preamble. The index of the subcarrier is from 0 to 11, the index of the time slot is from 0 to 3, and the index of the candidate frequency hopping pattern is from 0 to K-1. The sub-carrier transmitted in the l-th time slot determined by the k-th candidate frequency hopping pattern is the sub-carrier m _k,l . The sub-carrier index m _k,l satisfies:

Further, one slot may include N OFDM symbols, where N may be 14. The index of the OFDM symbol can be from 0 to N-1.

As mentioned above, the subcarrier transmitted in the lth slot determined by the kth candidate frequency hopping pattern is the subcarrier m _k,l , that is to say, it is used in each OFDM symbol in the lth slot The sub-carrier transmitted by the PRACH preamble is the sub-carrier m _k,l . Map x(n) on the nth OFDM symbol in the lth slot, and then generate the OFDM symbol.

The sequence x(n) can be a predefined sequence.

Further, the sequence x(n) may be a complex number sequence.

E.g,

Among them, j is an imaginary unit, the square of j is equal to -1, and π represents the circumference of the circle.

It can be stipulated by the agreement or set in advance.

E.g,

It can be as shown in Table 2.

Table 2

The frequency hopping units in the K candidate frequency hopping patterns may all be the same sequence in the code domain, and the length of the sequence may be 14.

When the frequency domain resources that can be used for PRACH preamble transmission include 12 subcarriers, the number of candidate frequency hopping patterns in the prior art is 12, and in the embodiment of the present application, K may be greater than 12, for example, K may be 24. A terminal device can arbitrarily select a candidate frequency hopping pattern from the 24 candidate frequency hopping patterns to send the PRACH preamble.

When K is 24, if 4 terminal devices simultaneously transmit PRACH preambles, s frequency hopping patterns are randomly selected from the generated 24 candidate frequency hopping patterns, and s=4. A terminal device needs to determine 4 frequency hopping units according to the candidate frequency hopping pattern, that is, determine the corresponding subcarriers on the 4 time slots. A total of 16 sub-carriers need to be determined for 4 terminal devices,

Represents the corresponding subcarrier on slot 1 determined by the candidate frequency hopping pattern selected by UE1. It should be understood that this expression only takes the terminal device as the UE as an example, and should not be regarded as a limitation to the embodiment of the present application. Since the above 4 candidate frequency hopping patterns may overlap, for example,

Then, the overlapping subcarriers determined by the above 4 candidate frequency hopping patterns, that is, the 4 candidate frequency hopping patterns include 3 identical frequency hopping units. The number of non-overlapping subcarriers determined by the 4 candidate frequency hopping patterns is 13, that is, the 4 candidate frequency hopping patterns include 13 different frequency hopping units. According to the criterion of the Bloom filter, 13=(1-ε)×L×s, the coefficient ε=3/16 corresponding to the Bloom filter is obtained. For the receiver of the network equipment, the more the number of non-overlapping subcarriers in the 4 candidate frequency hopping patterns, that is, the more the number of different frequency hopping units in the 4 candidate frequency hopping patterns, the more the network equipment The four terminal devices mentioned above can be identified with a greater probability according to the compressed sensing detection algorithm. That is to say, the smaller the coefficient ε corresponding to the Bloom filter, the better the detection performance of the network equipment based on the compressed sensing detection algorithm. For example, K=24 and θ=23963 are selected, and 24 candidate frequency hopping patterns are generated according to the above calculation method of the subcarrier index. According to the simulation result, 4 candidate frequency hopping patterns are randomly selected from the generated 24 candidate frequency hopping patterns, and the probability that the 4 candidate frequency hopping patterns includes 13 different frequency hopping units is greater than P=96%.

FIG. 5 shows a schematic diagram of 4 candidate frequency hopping patterns among K candidate frequency hopping patterns in an embodiment of the present application. Fig. 5 shows the subcarriers transmitted on 4 time slots determined by 4 candidate frequency hopping patterns. It should be noted that the candidate frequency hopping pattern in FIG. 5 only uses one time domain resource unit as one time slot and one frequency domain resource unit as one subcarrier as an example, and does not limit the solution structure of the embodiment of the present application. The 4 candidate frequency hopping patterns shown in FIG. 5 include the same frequency hopping unit, that is, there is a certain overlap between the 4 candidate frequency hopping patterns. In Figure 5, the subcarriers are indexed from 0 to 11 from bottom to top, and the time slots are indexed from 0 to 3 from left to right. The frequency hopping pattern 1 and the frequency hopping pattern 3 include the same frequency hopping unit, that is, the frequency hopping unit corresponding to the time slot 1 and the subcarrier 6. The frequency hopping pattern 2 and the frequency hopping pattern 3 include the same frequency hopping unit, that is, the frequency hopping unit corresponding to the subcarrier 11 in the time slot 2. When 4 terminal devices select the 4 frequency hopping patterns shown in Figure 5 respectively, although the different frequency hopping patterns partially overlap, the network device can still distinguish these 4 terminals with a greater probability through the compressed sensing detection algorithm. equipment.

According to the solution of the embodiment of the present application, the candidate frequency hopping patterns are allowed to include the same frequency hopping unit, that is, there is partial overlap between the candidate frequency hopping patterns, which can greatly increase the number of candidate frequency hopping patterns. In addition, the above-mentioned method of generating candidate frequency hopping patterns can control the degree of overlap of frequency hopping patterns, that is, control the bloom filter design coefficient, and the network device side or terminal device side can detect the first data through the compressed sensing algorithm, thereby improving the detection accuracy.

Form 2

A frequency hopping unit includes a frequency domain resource unit in the frequency domain, and the frequency hopping unit includes a time domain resource unit in the time domain, and the frequency hopping unit includes a code domain resource unit in the code domain. The code domain resource unit is one of V candidate code domain resource units, where V is an integer greater than 1.

Or it can be understood that the candidate frequency hopping pattern can determine frequency domain resource units corresponding to different time domain resource units, and determine code domain resource units corresponding to different time domain resource units. Different frequency hopping units in the K candidate frequency hopping patterns may correspond to different code domain resource units in the code domain.

The first data may include one or more code domain resource units. For example, the first data may include the aforementioned one code domain resource unit, that is, the first data is one of V candidate code domain resource units. The first data corresponding to different time domain resource units may be the same or different. The terminal device or the network device may map the first data corresponding to each of the L frequency hopping units to the time domain resource unit and the frequency domain resource unit corresponding to the frequency hopping unit according to the candidate frequency hopping pattern. For another example, the first data may include L code domain resource units in the above L frequency hopping units, and the L code domain resource units may be the same or different. The terminal device or the network device may map the L code domain resource units in the first data to the time domain resource unit and the frequency domain resource unit corresponding to each of the L frequency hopping units according to the candidate frequency hopping pattern. .

Specifically, the frequency domain resources that can be used to map the first data may include M frequency domain resource units. The frequency domain resource units included in the frequency domain resources that can be used to map the first data can be understood as candidate frequency domain resource units. The frequency domain resource unit corresponding to one frequency hopping unit is one of the above M frequency domain resource units. A candidate frequency hopping pattern may include L frequency hopping units. L may be equal to the number of corresponding time domain resource units during the transmission of the first data. The terminal device or the network device maps the first data to the time-frequency resource corresponding to the first frequency hopping pattern. The first frequency hopping pattern is one of a plurality of candidate frequency hopping patterns. The candidate frequency hopping pattern is used to determine the frequency domain resource unit corresponding to each of the L time domain resource units, and to determine the code domain resource unit corresponding to each of the L time domain resource units .

The description of the time domain resource unit and the frequency domain resource unit is as described in Form 1 above, and will not be repeated here.

Exemplarily, one code domain resource unit may be a sequence. The V candidate code domain resource units may be V candidate sequences, and the V candidate sequences may be orthogonal to each other.

Exemplarily, when one time domain resource unit is one PRACH symbol group, one frequency domain resource unit is one subcarrier, and one code domain resource unit is one sequence, the candidate frequency hopping pattern determines the transmission of different PRACH symbol groups. Subcarriers, and determine the sequence of transmission of different PRACH symbol groups.

The frequency hopping pattern is described below by taking a time domain resource unit as a PRACH symbol group, a frequency domain resource unit as a subcarrier, a code domain resource unit as a sequence, and the first data being a PRACH preamble as an example.

For example, the time domain resource for a PRACH preamble transmission may include 4 PRACH symbol groups, and L may be equal to the number of time domain resource units included in the 4 PRACH symbol groups, that is, L is 4. A candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarriers transmitted by each PRACH symbol group in the 4 PRACH symbol groups, and determine the sequence transmitted by each PRACH symbol group in the 4 PRACH symbol groups.

For another example, to repeat PRACH preamble transmission twice, 8 PRACH symbol groups are required. That is, the time domain resources of two PRACH preamble transmissions include 8 PRACH symbol groups. L may be equal to the number of time domain resource units included in the 8 PRACH symbol groups, that is, L is 8. That is, a candidate frequency hopping pattern includes 8 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarriers transmitted by each PRACH symbol group in the 8 PRACH symbol groups, and determine the sequence transmitted by each PRACH symbol group in the 8 PRACH symbol groups.

Exemplarily, when one time domain resource unit is one time slot, one frequency domain resource unit is one subcarrier, and one code domain resource unit is one sequence, the candidate frequency hopping pattern determines the transmission of different time slots. Subcarriers, and determine the sequence of transmission in different time slots.

The frequency hopping pattern is described below by taking a time domain resource unit as a time slot, a frequency domain resource unit as a subcarrier, a code domain resource unit as a sequence, and the first data being a PRACH preamble as an example.

For example, the time domain resource for one PRACH preamble transmission may include 1 time slot, and the time domain resource for repeated PRACH preamble transmission 4 times includes 4 time slots. In this case, L may be equal to the number of time domain resource units contained in 4 time slots, that is, the number of repeated transmissions of the PRACH preamble, that is, L is 4. A candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarriers transmitted in each of the 4 time slots and the sequence of transmission in each time slot.

Optionally, the index of the frequency domain resource unit may be preset, and the index of the code domain resource unit may also be preset.

Specifically, the frequency hopping unit can be determined by determining the index of the frequency domain resource unit, the index of the time domain resource unit, and the index of the code domain resource unit of the frequency hopping unit, and further, by determining L of a candidate frequency hopping pattern The index of the frequency domain resource unit of the frequency hopping unit, the index of the time domain resource unit, and the index of the code domain resource can respectively determine the positions of the L frequency hopping units on the aforementioned time-frequency resource and code domain resource.

The index of the preset frequency domain resource unit and the index of the code domain resource unit can also be understood as the index of the frequency domain resource unit of the preset frequency hopping unit, the index of the code domain resource unit of the frequency hopping unit, and the index of the hop. Correspondence between the indexes of the time domain resource unit of the frequency unit.

For example, the index of the frequency domain resource unit and the index of the code domain resource unit can be obtained through a predefined table, or it can be said that the candidate frequency hopping pattern is obtained through a predefined table. Table 3 shows a predefined table of candidate frequency hopping patterns. It should be understood that Table 3 is only for illustration, and the embodiment of the present application does not limit the correspondence between the index of the frequency domain resource unit, the index of the time domain resource unit, and the index of the code domain resource unit. Specifically, the predefined table can give L frequency hopping units in a candidate frequency hopping pattern, that is, give the positions of frequency domain resource units, time domain resource units, and code domain resource units corresponding to the L frequency hopping units. The location, or the index of the frequency domain resource unit, the index of the time domain resource unit, and the index of the code domain resource unit corresponding to the L frequency hopping units are given. That is to say, the candidate frequency hopping pattern obtained through the predefined table can be understood as the predefined table giving the corresponding frequency domain resource unit on each time domain resource unit and the corresponding code domain resource unit on each time domain resource unit. In other words, the index of the frequency domain resource unit corresponding to each time domain resource unit and the index of the code domain resource unit corresponding to each time domain resource unit are given.

Alternatively, the index of the frequency domain resource unit and the index of the code domain resource unit may also be calculated according to certain rules.

Exemplarily, determining L frequency hopping units in a candidate frequency hopping pattern may be first determining the index of the frequency domain resource unit of each frequency hopping unit in the L frequency hopping units, and then determining the index of each frequency hopping unit The index of the code domain resource unit.

Specifically, the index of the aforementioned frequency domain resource unit may be determined in the manner in Form 1.

Exemplarily, determining L frequency hopping units in a candidate frequency hopping pattern may be to simultaneously calculate the index of the frequency domain resource unit and the index of the code domain resource unit corresponding to each frequency hopping unit on the corresponding time domain resource unit .

In the case that the code domain resource unit is a sequence, the length of the sequence is related to the number of symbols N in the above-mentioned time domain resource unit.

The sequence can be a predefined sequence.

As mentioned above, the index of the frequency domain resource unit corresponding to the lth time domain resource unit determined by the kth candidate frequency hopping pattern is the frequency domain resource unit m _k,l , that is to say, at the kth candidate frequency hopping pattern The corresponding frequency domain resource unit in each OFDM symbol in the l th time domain resource unit in the pattern is a frequency domain resource unit m _k,l . Mapping on the nth OFDM symbol in the lth time domain resource unit

Exemplarily, the time domain resource for one PRACH preamble transmission may include one time slot, and the frequency domain resource includes one subcarrier. The time domain resource for repeating the PRACH preamble transmission 4 times includes 4 time slots, and the frequency domain resource includes one subcarrier. L is 4, that is, a candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarriers transmitted on each of the 4 time slots and determine the sequence of transmission on each of the 4 time slots. The frequency domain resources that can be used for PRACH preamble transmission include M subcarriers, and M can be 12. The code domain resources that can be used for PRACH preamble transmission are 4 orthogonal sequences, and V is 4. The PRACH preamble is repeatedly sent L times in the time domain, and each time a frequency hopping unit can be used for transmission, that is, the time domain resource of a transmission includes 1 time slot, the frequency domain resource includes 1 subcarrier, and the code domain resource is a sequence . The terminal device can select one candidate frequency hopping pattern from the K candidate frequency hopping patterns to transmit the PRACH preamble. The index of the sequence is from 0 to 3, the index of the subcarrier is from 0 to 11, the index of the time slot is from 0 to 3, and the index of the candidate frequency hopping pattern is from 0 to K-1. The subcarrier transmitted in the lth time slot determined by the kth candidate frequency hopping pattern is the subcarrier m _k,l , and the sequence transmitted in the lth time slot is the sequence v _k,l . A frequency hopping unit can be determined by the index of the time slot, the index of the subcarrier, and the index of the sequence.

When the frequency domain resources that can be used for PRACH preamble transmission include 12 subcarriers, the number of candidate frequency hopping patterns in the prior art is 12, and in the embodiment of the present application, the number of orthogonal sequences is 4, then the candidate frequency hopping patterns The number of patterns may be 48, and the candidate frequency hopping patterns in the embodiment of the present application allow overlap, that is, K may be greater than 48.

If 4 terminal devices simultaneously transmit the PRACH preamble, s frequency hopping patterns are randomly selected from the generated K candidate frequency hopping patterns, and s=4. A terminal device needs to determine 4 frequency hopping units according to the candidate frequency hopping pattern, that is, determine the corresponding (m _{k, l} , v _{k, l} ) on the 4 time slots. 4 terminal devices need to determine a total of 16 (m _{k, l} , v _{k, l} ), similar to form 1, if the 4 candidate frequency hopping patterns include 3 overlapping (m _{k, l} , v _{k, l} ) , That is, 4 candidate frequency hopping patterns contain 3 identical frequency hopping units, that is, 4 candidate frequency hopping patterns contain 13 non-overlapping (m _k,l ,v _k,l ), that is, 4 candidate hopping patterns The frequency pattern contains 13 different frequency hopping units. According to the criterion of the Bloom filter, 13=(1-ε)×L×s, the coefficient ε=3/16 corresponding to the Bloom filter is obtained. For example, K=48 and θ=23963 are selected, and 48 candidate frequency hopping patterns are generated according to the above-mentioned method for determining the index of the subcarrier and the index of the sequence. According to the simulation result, 4 candidate frequency hopping patterns are randomly selected from the generated 48 candidate frequency hopping patterns, and the probability that the 4 candidate frequency hopping patterns includes 13 different frequency hopping units is greater than P=99%.

FIG. 6 shows a schematic diagram of 4 candidate frequency hopping patterns among K candidate frequency hopping patterns according to another embodiment of the present application. Fig. 6 shows the subcarriers and sequences transmitted on 4 time slots determined by 4 candidate frequency hopping patterns. It should be noted that the candidate frequency hopping pattern in FIG. 5 only uses one time domain resource unit as a time slot, one frequency domain resource unit as a subcarrier, and one code domain resource unit as a sequence as an example, and will not be implemented in this application. The plan of the example is limited. The 4 candidate frequency hopping patterns shown in FIG. 6 include the same frequency hopping unit, that is, there is a certain overlap between the 4 candidate frequency hopping patterns. In Figure 6, the subcarriers are indexed from 0 to 11 from bottom to top, the time slots are indexed from 0 to 3 from left to right, and the sequence is indexed from 0 to 3 from bottom to top. The frequency hopping pattern 1 and the frequency hopping pattern 3 include the same frequency hopping unit, that is, the frequency hopping unit corresponding to the time slot 1, the subcarrier 1 and the sequence 2. The frequency hopping pattern 2 and the frequency hopping pattern 3 include the same frequency hopping unit, that is, the frequency hopping unit corresponding to the time slot 2, the subcarrier 2 and the sequence 3. It can be seen from Figure 6 that frequency hopping pattern 1 and frequency hopping pattern 2 do not contain the same frequency hopping unit, and the subcarriers determined by frequency hopping pattern 1 and frequency hopping pattern 2 to be transmitted on time slot 0 are all subcarrier 2. , The sequences transmitted on the time slot 0 determined by the two are different, so the frequency hopping pattern 1 and the frequency hopping pattern 2 do not overlap on the subcarrier 2 of the time slot 0, that is to say, the frequency hopping pattern 1 and the frequency hopping pattern 2 are in time. Slot 0 does not contain the same frequency hopping unit.

According to the solution of the embodiment of the present application, the candidate frequency hopping patterns are allowed to contain the same frequency hopping unit, that is, there is partial overlap between the candidate frequency hopping patterns, which increases the number of candidate frequency hopping patterns, and at the same time introduces codes on a single frequency domain resource unit The domain resource unit, such as introducing a time domain orthogonal sequence, can further increase the number of candidate frequency hopping patterns and reduce the probability of collision. In addition, the above-mentioned method of generating candidate frequency hopping patterns can control the degree of overlap of frequency hopping patterns, that is, control the bloom filter design coefficient, and the network equipment side or the terminal equipment side can detect the uplink signal through the compressed sensing algorithm, thereby improving the detection efficiency. accuracy.

A frequency hopping unit includes a frequency domain resource unit in the frequency domain, and the frequency hopping unit includes a time domain resource unit in the time domain, corresponding to a sub-hop on the frequency domain resource unit and the time domain resource unit Frequency pattern, the sub-frequency hopping pattern is one of H candidate sub-frequency hopping patterns, wherein one candidate sub-frequency hopping pattern in the H candidate sub-frequency hopping patterns includes Q sub-frequency hopping units, and Q is greater than An integer of 1.

Or it can also be understood that the candidate frequency hopping pattern can determine the frequency domain resource units corresponding to different time domain resource units, and determine the corresponding candidate sub frequency hopping patterns on different time domain resource units. In a candidate frequency hopping pattern, the correspondence between the time domain resource unit and the frequency domain resource unit may be one of Y candidate correspondences. For ease of understanding, the Y candidate correspondences can be regarded as Y candidate intermediate patterns, that is, the candidate intermediate patterns can be used to determine the time domain resource unit and the frequency domain resource unit in each of the L frequency hopping units. The corresponding relationship. The candidate frequency hopping pattern may determine a candidate intermediate pattern and corresponding candidate sub-frequency hopping patterns on different time domain resource units in the candidate intermediate pattern. The candidate intermediate patterns corresponding to different candidate frequency hopping patterns may be the same or different.

A sub-frequency hopping unit includes a sub-frequency domain resource unit in the frequency domain, and the sub-frequency hopping unit includes a sub-time domain resource unit in the time domain.

Specifically, the frequency domain resources that can be used to map the first data may include M frequency domain resource units. The frequency domain resource units included in the frequency domain resources that can be used to map the first data can be understood as candidate frequency domain resource units. The frequency domain resource unit corresponding to one frequency hopping unit is one of the above M frequency domain resource units. A candidate frequency hopping pattern may include L frequency hopping units. L may be equal to the number of corresponding time domain resource units during the transmission of the first data. The terminal device or the network device maps the first data to the time-frequency resource corresponding to the first frequency hopping pattern. The first frequency hopping pattern is one of a plurality of candidate frequency hopping patterns. The candidate frequency hopping pattern is used to determine the frequency domain resource unit corresponding to each of the L time domain resource units, and to determine the candidate sub-hopping frequency corresponding to each of the L time domain resource units pattern. The length of one sub-time domain resource unit is less than the length of one time-frequency resource unit. One sub-time-domain resource unit may include at least one frame, at least one sub-frame, at least one slot, at least one mini-slot, or at least one time-domain symbol. As long as the length of the sub-time domain resource unit is less than the length of the time domain resource unit, the embodiment of the present application does not limit the form of the sub-time domain resource unit.

Wherein, Q may be equal to the number of sub-time-domain resource units included in one time-domain resource unit.

The frequency domain range of one sub-frequency domain resource unit is smaller than the frequency domain range of one frequency domain resource unit. One sub-frequency domain resource unit may include at least one carrier, at least one component carrier, at least one bandwidth part, at least one resource block group, at least one physical resource block group, at least one resource block, or at least one subcarrier. As long as the frequency domain range in one sub-frequency domain resource unit is smaller than the frequency domain range in one frequency domain resource unit, the embodiment of the present application does not limit the form of the sub-frequency domain resource unit.

As shown above, one frequency domain resource unit may include multiple subcarriers, for example, one subcarrier group.

Exemplarily, when one time domain resource unit is a time slot, and one frequency domain resource unit is a subcarrier group, the candidate frequency hopping pattern determines the subcarrier groups corresponding to different time slots, and determines the subcarrier groups corresponding to different time slots. Sub-frequency hopping pattern.

The frequency hopping pattern is described below by taking one time domain resource unit as a time slot, one frequency domain resource unit as a subcarrier group, and the first data being a PRACH preamble as an example.

For example, the time domain resource of a PRACH preamble transmission may include 1 time slot, and the frequency domain resource may include one subcarrier. The time domain resource for repeating the PRACH preamble transmission 4 times includes 4 time slots, and the frequency domain resource includes one subcarrier. In this case, L is the number of repeated transmissions of the PRACH preamble, and L is 4, that is, a candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the subcarrier group corresponding to each of the 4 time slots, and to determine the candidate subcarrier pattern corresponding to each of the 4 time slots. One slot can include N OFDM symbols. When one sub-time domain resource unit is one OFDM symbol, and one sub-frequency domain resource unit is one sub-carrier, the candidate sub-frequency hopping pattern is used to determine the N OFMD symbols. The corresponding sub-carrier on each OFMD symbol. Or it can also be understood that the subcarriers corresponding to different OFDM symbols may be different.

Optionally, the index of the frequency domain resource may be preset, and the index of the candidate sub-frequency hopping pattern may be preset.

Specifically, the frequency hopping unit can be determined by determining the index of the frequency domain resource unit of the frequency hopping unit, the index of the time domain resource unit, and the index of the candidate sub-frequency hopping pattern. Further, by determining the index of the frequency domain resource unit, the index of the time domain resource unit, and the index of the candidate sub-frequency hopping pattern of the L frequency hopping units in a candidate frequency hopping pattern, it can be determined that the L frequency hopping units are in the above-mentioned The location of the time-frequency resource.

The index of the preset frequency domain resource unit and the index of the candidate sub-frequency hopping pattern can also be understood as the index of the preset frequency domain resource unit of the frequency hopping unit, the index of the candidate sub-frequency hopping pattern of the frequency hopping unit, and Correspondence between the indexes of the time domain resource units of the frequency hopping unit. As mentioned above, the candidate intermediate pattern can be used to determine the correspondence between the frequency domain resource unit in each frequency hopping unit in the L frequency hopping units and the time domain resource unit in the frequency hopping unit. Therefore, the preset index of the frequency domain resource unit can also be understood as a preset candidate intermediate pattern.

For example, the index of the frequency domain resource unit and the index of the candidate sub-frequency hopping pattern can be obtained through a predefined table, or it can be said that the candidate frequency hopping pattern is obtained through a predefined table. Table 4 shows a predefined table of candidate frequency hopping patterns. The first two rows in Table 4 show the candidate intermediate pattern corresponding to the candidate frequency hopping pattern. It should be understood that Table 4 is only for illustration, and the embodiment of the present application does not limit the correspondence between the indexes of frequency domain resource units, the indexes of time domain resource units, and the indexes of candidate sub-frequency hopping patterns.

Alternatively, the index of the frequency domain resource unit and the index of the candidate sub-frequency hopping pattern may also be calculated according to a certain rule. Or it can be understood that the index of the candidate intermediate pattern and the index of the candidate sub-frequency hopping pattern can also be calculated according to certain rules.

Exemplarily, determining the L frequency hopping units in a candidate frequency hopping pattern may be first determining the candidate intermediate pattern, that is, first determining the frequency domain resource unit index of each frequency hopping unit in the L frequency hopping units, and then Determine the index of the candidate sub-frequency hopping pattern for each frequency hopping unit.

Specifically, the index of the frequency domain resource unit in the candidate intermediate pattern may be determined in the manner in form 1.

Exemplarily, determining the L frequency hopping units in a candidate frequency hopping pattern may be to simultaneously calculate the index of the candidate intermediate pattern and the index of the corresponding candidate sub-frequency hopping pattern on the time domain resource unit in each frequency hopping unit.

Optionally, the index of the candidate intermediate pattern is related to L and H, and the index of the candidate sub-frequency hopping pattern is related to L and H.

Optionally, the index of the candidate intermediate pattern is also related to Y. The index of the aforementioned candidate sub-frequency hopping pattern is also related to Y.

The initialization value c _{init of the} gold sequence may be predefined or configured by the network device for the terminal device. θ can be pre-defined or configured by the network device for the terminal device. Further, one time domain resource unit may include N OFDM symbols, and the index of the OFDM symbol may be from 0 to N-1.

As mentioned above, the candidate intermediate pattern determined by the k-th candidate frequency hopping pattern is the candidate intermediate pattern y _k , and the frequency-domain resource unit corresponding to the l-th time-domain resource unit in the candidate intermediate pattern y _{k is the frequency-domain resource unit} m _k,l , in the frequency domain resource unit, the frequency domain resource corresponding to each OFDM symbol can be determined by the candidate sub-frequency hopping pattern. Map x(n) on the nth OFDM symbol in the lth time domain resource unit, and then generate the OFDM symbol.

The sequence x(n) can be a predefined sequence.

Further, the sequence x(n) may be a complex number sequence.

E.g,

It can be stipulated by the agreement or set in advance.

For example, all frequency hopping units in the K candidate frequency hopping patterns may have the same sequence in the code domain.

Take a time domain resource unit as a time slot, and a frequency domain resource unit as a subcarrier group. The subcarrier group includes 4 subcarriers, 4 candidate sub-hopping patterns, and the first data is the PRACH preamble as an example. The above-mentioned frequency domain resource unit and the index of candidate sub-frequency hopping patterns will be described.

Exemplarily, the time domain resource for one PRACH preamble transmission may include one time slot, and the frequency domain resource includes one subcarrier. The time domain resource for repeating the PRACH preamble transmission 4 times includes 4 time slots, and the frequency domain resource includes one subcarrier. L is 4, that is, a candidate frequency hopping pattern includes 4 frequency hopping units. The candidate frequency hopping pattern is used to determine the sub-carrier group and the corresponding sub-frequency hopping pattern transmitted on each of the 4 time slots. The frequency domain resources that can be used for PRACH preamble transmission include 12 subcarriers, and M is 3. The PRACH preamble is repeatedly sent L times in the time domain, and each time a frequency hopping unit can be used for transmission, that is, the time domain resource of one transmission includes 1 time slot, and the frequency domain resource includes 1 subcarrier. The terminal device can select one candidate frequency hopping pattern from the K candidate frequency hopping patterns to transmit the PRACH preamble. The index of the subcarrier group is from 0 to 2, the index of the time slot is from 0 to 3, the index of the candidate frequency hopping pattern is from 0 to K-1, and the index of the candidate sub frequency hopping pattern is from 0 to H-1. The candidate intermediate pattern determined by the k-th candidate frequency hopping pattern is the candidate intermediate pattern y _k , and the corresponding candidate sub-frequency hopping pattern corresponding to the l-th time domain resource unit is the sub-frequency hopping pattern h _k,l , in the middle of the candidate The frequency domain resource unit corresponding to the l th time domain resource unit in the pattern y _k _{is the frequency domain resource unit m k,l} . For ease of description, it can be understood that a candidate frequency hopping pattern corresponds to a two-dimensional array (m _{k, l} , h _{k, l} ) on a time slot.

The index of the frequency domain resource unit and the index of the candidate sub-frequency hopping pattern satisfy:

Further, one slot may include N OFDM symbols, where N may be 14. The index of the OFDM symbol can be from 0 to 13. The sub-frequency hopping unit in the candidate sub-frequency hopping pattern includes a sub-time domain resource unit in the time domain and a sub-frequency domain resource unit in the frequency domain. The sub-time domain resource unit may be an OFDM symbol. The domain resource unit may be one subcarrier. The candidate sub-frequency hopping pattern may be used to determine sub-carriers corresponding to different OFDM symbols.

As mentioned above, the candidate intermediate pattern determined by the k-th candidate frequency hopping pattern is the candidate intermediate pattern y _k , and the corresponding candidate sub-frequency hopping pattern corresponding to the l-th time domain resource unit is the sub-frequency hopping pattern h _{k, l} , the frequency-domain resource unit corresponding to the l-th time-domain resource unit in the candidate intermediate pattern y _k _{is the frequency-domain resource unit m k,l} , or it can also be understood as in each OFDM symbol in the l-th slot The subcarrier used for PRACH preamble transmission is a subcarrier in the subcarrier group _mk,l , and the subcarrier corresponding to each OFDM symbol is determined by the subfrequency hopping pattern corresponding to the time slot. Map x(n) on the nth OFDM symbol in the lth slot, and then generate the OFDM symbol.

The sequence x(n) can be a predefined sequence.

Further, the sequence x(n) may be a plural sequence.

E.g,

It can be stipulated by the agreement or set in advance.

E.g,

It can be as shown in Table 2 in Form 1.

When the frequency domain resources that can be used for PRACH preamble transmission include 12 sub-carriers, the number of candidate frequency hopping patterns in the prior art is 12, and in the embodiment of the present application, the number of candidate frequency hopping patterns is 4, and the number of candidate frequency hopping patterns is 4. The frequency pattern can be an orthogonal sub-frequency hopping pattern, and the number of sub-carrier groups is 3. Since overlap is allowed between candidate frequency hopping patterns, the number of candidate intermediate patterns Y can be 9, so the number of candidate frequency hopping patterns can be Is 36.

If 4 terminal devices simultaneously transmit the PRACH preamble, s frequency hopping patterns are randomly selected from the generated K candidate frequency hopping patterns, and s=4. A terminal device needs to determine 4 frequency hopping units according to the candidate frequency hopping pattern, that is, determine the corresponding (m _k,l ,h _k,l ) on the 4 time slots. 4 terminal devices need to determine a total of 16 (m _{k, l} , h _{k, l} ), similar to form 1, if the 4 candidate frequency hopping patterns include 3 overlapping (m _{k, l} , h _{k, l} ) , That is, 4 candidate frequency hopping patterns contain 3 identical frequency hopping units, that is, 4 candidate frequency hopping patterns contain 13 non-overlapping (m _k,l ,h _k,l ), that is, 4 candidate hopping patterns The frequency pattern contains 13 different frequency hopping units. According to the criterion of the Bloom filter, 13=(1-ε)×L×s, the coefficient ε=3/16 corresponding to the Bloom filter is obtained. For example, K=48 and θ=23963 are selected, and 36 candidate frequency hopping patterns are generated according to the above-mentioned method for determining the index of the subcarrier group and the index of the candidate sub-frequency hopping pattern. According to the simulation result, 4 candidate frequency hopping patterns are randomly selected from the generated 36 candidate frequency hopping patterns, and the probability that the 4 candidate frequency hopping patterns includes 13 different frequency hopping units is greater than P=98.3%.

FIG. 7 shows a schematic diagram of 4 candidate frequency hopping patterns among K candidate frequency hopping patterns according to another embodiment of the present application. FIG. 7 shows the sub-carrier groups and candidate sub-frequency hopping patterns that are determined by the 4 candidate frequency hopping patterns and are transmitted on 4 time slots. It should be noted that the candidate frequency hopping pattern in Figure 6 only uses one time domain resource unit as a time slot, one frequency domain resource unit as a subcarrier group, one sub-time domain resource unit as an OFDM symbol, and one sub-frequency resource unit as a subcarrier group. The domain resource unit is a subcarrier as an example, and does not limit the solution of the embodiment of the present application. Not all candidate frequency hopping patterns are shown in FIG. 7, not all OFDM symbols are shown in one slot, and complete candidate sub-hopping patterns are not shown. The 4 candidate frequency hopping patterns shown in FIG. 7 include the same frequency hopping unit, that is, there is a certain overlap between the 4 candidate frequency hopping patterns. In Figure 7, the subcarrier group is indexed from 0 to 2 from bottom to top, and the time slot is indexed from 0 to 3 from left to right. The frequency hopping pattern 1 and the frequency hopping pattern 3 include the same frequency hopping unit, that is, the time slot 1, the subcarrier group 1, and the frequency hopping unit corresponding to the sub-frequency hopping pattern shown in the figure. The frequency hopping pattern 2 and the frequency hopping pattern 3 include the same frequency hopping unit, that is, the time slot 2, the sub-carrier group 2 and the frequency hopping unit corresponding to the sub-frequency hopping pattern shown in the figure. It can be seen from Figure 7 that the frequency hopping pattern 1 and the frequency hopping pattern 2 do not contain the same frequency hopping unit, and the corresponding subcarrier groups of the frequency hopping pattern 1 and the frequency hopping pattern 2 on the time slot 0 are all subcarrier group 2. , But the two corresponding sub-frequency hopping patterns are different, so the frequency hopping pattern 1 and the frequency hopping pattern 2 do not overlap on the time slot 0, that is to say, the frequency hopping pattern 1 and the frequency hopping pattern 2 do not contain the same on the time slot 0 Frequency hopping unit.

In this embodiment, the minimum frequency hopping unit is allowed to overlap between the frequency hopping patterns, but the subcarrier patterns are not allowed to overlap.

According to the solution of the embodiment of this application, the candidate frequency hopping patterns are allowed to contain the same frequency hopping unit, that is, there is partial overlap between the candidate frequency hopping patterns, which increases the number of candidate frequency hopping patterns. The introduction of sub-frequency hopping patterns on the resource unit, that is, the introduction of two layers of frequency hopping, which increases the dimension of the frequency hopping unit, can further increase the number of candidate frequency hopping patterns, and reduce the conflict of terminal equipment or network equipment during signal transmission. possibility. For a candidate frequency hopping pattern, different sub-frequency hopping patterns are orthogonal, which improves the probability of correct detection to a certain extent, thereby improving the detection performance of network equipment or terminal equipment. In addition, the above-mentioned method of generating candidate frequency hopping patterns can control the degree of overlap of frequency hopping patterns, that is, control the bloom filter design coefficient, and the network device side or the terminal device side can detect the first data through the compressed sensing algorithm, thereby improving the detection Accuracy.
